Espen O. 5/5 Verified April 3, 2026

STI 2011 Brass Magwell | IPSC/USPSA Open

Makes a very nice balance to the polymer grip. Overall fit and finish top notch. Note that black finish is very delicate and will wear fast. Got some brass colored spots before it even was installed.

STI 2011 Brass Magwell | IPSC/USPSA Open

I took a chance & bought one to try on my staccato’s. Fits like a glove on full size grips both gen 1 & 2. Did not fit on my C2 unless I did a little dremeling.

Customer photo review of STI 2011 Mag well | Brass | IPSC/USPSA Open Division

Love the weight and angles of this magwell. Works great on my Chambers Custom NightFighter. It can be a little difficult getting the pin back on but once it’s installed it stays put. I’m very happy with this magwell.

Fits perfectly on Staccato XC. Beautiful durable finish and the added wait really reduces felt recoil and increases stability.

STI 2011 Staccato Magwell | Brass | IPSC/USPSA Open Division

Magwell is great It’s a tight fit and could be made to line up with the pin hole on the grips little better. Other than that I love it. It’s huge and the weight helps with recoil.
